As part of the extension to the National Museum Zurich, the old building was renovated and expanded.

Walo Bertschinger AG was entrusted with some of the surfacing work. The two-layer SURFATEX® terrazzo flooring system, which was installed after being chosen by the planners for the forecourt, is just as diverse as the history and culture of Switzerland. This seamless, honed floor covering fulfils both the demanding aesthetic and technical requirements and has proved itself over thousands of years. An eminently suitable choice, as this is a natural material, which impresses with its durability as well as its vibrancy and elegance.
